Yuan Longping, a great scientist,is the first person to develop a kind of hybrid rice(杂交水稻) which helps fight hunger in China.
Food was a big problem in China in the past. This was because China had 22 percent of the world's population, but only 7 percent of its farmland.In the 1960s, China suffered (遭受)serious hunger.Millions of people died because they had no food.As an agronomy (农学) teacher.Yuan was very sad to see this. "How can I help them have enough food?" he thought.He decided to work on a kind of hybrid rice.It has a high output (产量).
At that time, other scientists didn't think hybrid rice was worth studying. But Yuan and his team worked on it every day. They took very good care of their rice seeds.
At last, in 1973, they grew a new kind of hybrid rice. This rice is strong. Farmers can grow it in many different kinds of farmland and also in bad weather. It can also fight disease. Its output was much greater than common kinds of rice. With the new kind, about 70,000,000 people could have food every year!
Yuan solved the food problem in China.But he is still working on rice.Before he retires (退休),he hopes to grow rice in the sea!

The World's Largest Insect
This giant insect can be used as a toy.A child ties one end of a string to a stick and the other end around the "neck" of an insect. Holding the stick, the child lets the insect go. With a loud whirring sound, the insect takes off, pulling the string in a large curve over the child's head. The child laughs as the stick jumps around. The child is African, and the toy is the African Goliath beetle, the largest insect in the world.
The Goliath is a true insect because it has six legs and a body that is divided into three parts. Like all beetles, it has two pairs of wings. The front pair are thick and stiff and protect the back pair, which are soft. It is these soft back wings that make the beetle fly forward. They also cause the loud whirring sound the beetle makes when it flies. To steer, the beetle twists and turns its legs the same way you steer a bike by turning its front wheel.

Where is the passage probably from ?
A.A story book . | B.A newspaper. | C.A student’s article | D.A science magazine . |
“BANG!” the door caused a reverberation (回声). It was just standing there, with father standing on one side, and I was on the other side. We were both in great anger. “Never set foot in this house again!” stormed father. I rushed out of the flat and ran along the street. The street lights were shining, causing rather a sad feeling.
A young father who held a child in his arms walked past me. I felt as if I saw my childhood from another space: happy and carefree. But now … I don’t know whether it is because I have grown up or because dad is getting old. We differ in our ways of thinking. He always put his opinions and codes of behavior on me. Whenever I do something wrong, he never admits it. We are just like two people coming from two different worlds. I wandered in the streets, until I had only the street lights to keep me company. When I finally reached the high-rise apartment block in which I lived ,I saw that the light was still on.
I thought to myself: “Is father waiting for me, or is he still angry with me?”
All the lights were off except father’s. Dad was always like this. Maybe he didn’t know how to express himself. After an argument he has the habit of creeping up(悄悄地来到) in my sleep. This was how he always was.He has been a leader for so long that telling everyone else what to do has become his second nature. With the key in hand, I was as nervous as I had ever been. At last, I decided to open the door. As soon as I opened the door tears ran down my cheeks. I suddenly realized that the iron(铁的) door that I had imagined between us did not exist at all. Love—it’s second to none.Decide which is the best order of the following according to what happened in the passage.
a. I opened the door and entered the house.
b. Sadly I ran out into the street.
c. I reached the place where I lived and saw my house still brightly lit.
d. I thought of my father’s kindness towards me.
